Toward Camouflage Colors by Electrochemical Copolymerization

Abstract

In this paper, a new electrochromic copolymer containing 6,9‐bis(2,3‐dihydrothieno[3,4‐b][1,4]dioxin‐5‐yl)‐1,2,3,4‐tetrahydrophenazine (EBE) and 4‐(9‐benzyl‐9H‐carbazol‐3‐yl)‐7‐(thiophen‐2‐yl)benzo[c][1,2,5]thiadiazole (CBT) in the main chain was reported. The homopolymers, (Poly(EBE) and Poly(CBT)), were also prepared via electrochemical polymerization and their electrochemical, spectroelectrochemical and electrochromic properties were analyzed in order to compare their properties with those of copolymer (Poly(EBE‐co‐CBT)). The copolymer exhibited good switching property for military camouflage necessities with color change from hues of brown to green. Furthermore, it has been tried to analyze the effects of combination of two donor‐acceptor‐donor (DAD) type monomers with different symmetries on the copolymer properties.
